I am residing in UK on Spouse Visa (Leave to Return). Before I moved to UK, I worked in Germany on EU Blue card for 3 years but left the job after I moved to the UK. Now, I have a job opportunity again from the same German company to work remotely while physically being in UK. I need to know if the German company or I need to follow any legal regulations to follow in order to work remotely for the German company remotely?
